Motor power control device and method

It will be appreciated that the bench mixer generally general motor (such as specified 350W) with small size, In：

At the slow-speed of revolution setting 1-3 with heavy load, output rotating speed can not be kept.

Under the high rotating speed setting of common load, due to the limitation of motor torsional moment capacity, output rotating speed can not be maintained.

Motor dimension must be carefully chosen causes motor temperature fast locking underload in turn to minimize motor rotor The raised risk of speed.If unit operates in the setting of the high rotating speed with top load, geared system can be damaged.

Relatively large general motor at the low setting 1-3 with heavy load, output rotating speed can be maintained, but by In motor input power higher, so motor temperature can compare miniature motor and increase more under the control of normal closed loop rotating speed Soon.This motor self-heating rate higher and moyor are less than miniature motor.In the setting slow-speed of revolution and peak efficiency rotating speed Between speed discrepancy away from more than more small-sized motor.Higher rotating speed is arranged, motor temperature is in desired temperature limiting It gradually increases.Moyor higher.For the higher rotating speed setting with top load, the torque and rotating speed that motor generates can Lead to gear failure, such as the gear teeth that fractures.

General motor is dimensionally similar to more small-sized motor, cannot be with the raising of low motor temperature Slow-speed of revolution setting performance under heavy load provides enough torques.Due to its smaller rated power, motor temperature increases to obtain ratio Large-scale general motor is slower.High rotating speed is arranged, motor cannot provide enough torques to meet the setting under normal load Rotating speed.

Usual general motor control for bench mixer can include the two methods in motor rotary speed closed-loop control In one kind.These motor rotary speed closed loop control methods are：

(a) there is the triacs power (watt) for the motor centrifugal switch for providing speed feedback Limit driving circuit.

(b) there is the triacs driving electricity for the Hall effect speed probe for providing speed feedback Road.

It will be appreciated that being controlled using triacs firing angle, power limit can be carried For.

With reference to figure 20A to Figure 20 C, by selectively switching triacs at different phase angles, Being transported to the mean power (watt) of motor can be controlled or be arranged.Shaded area indicates the power for being supplied to motor (when triacs is activated).This has selectively accessed a part of input power source AC waveforms.

Figure 20 A show the relatively small phase angle for selective enabling triacs, described Triacs is connected earlier after zero cross point.It will be appreciated that shaded area covering Most of sinusoidal voltage waveform 700, and then provide the output power of relatively high supply/generation.

Figure 20 B show the relatively intermediate phase angle for selective enabling triacs, institute Triacs is stated to be connected at the middle part of two zero cross points.It will be appreciated that shaded area covering The half of sinusoidal voltage waveform 702, and then provide the output power of supply/generation of rather moderate.

Figure 20 C show the relatively large phase angle for selective enabling triacs, described Triacs is later after zero cross point to be just switched on.Shaded area covers relatively small number of sine Voltage waveform 704, and then provide the output power of relatively low supply/generation.

With reference to figure 21A to Figure 20 D, control, quilt are cut by using the triacs AC waves of selectivity Being transported to the mean power (watt) of motor can be controlled or be arranged.

Figure 21 A show complete AC voltage waveforms 750.Processor module is able to detect that AC zero cross points, and is Half periods of one or more complete AC sinusoidal waveforms and be Turned on/off triacs.

Figure 21 B are shown cuts showing for (half period being removed from all 12 half periods) with relatively low wave Example voltage waveform 752 has relatively high numerical value by the watt of voltage waveform supply.

Figure 21 C show the example that (six half periods are removed from all 12 half periods) is cut with 50% wave Voltage waveform 754 has relatively intermediate numerical value by the watt of voltage waveform supply.

Figure 21 D are shown cuts showing for (eight half periods being removed from all 12 half periods) with relatively high wave Example property voltage waveform 756 has relatively low numerical value by the watt of voltage waveform supply.

With the motor centrifugal switch as velocity feedback exemplary triacs power (watt It is special) limitation driving circuit is only disclosed by way of example.In this embodiment, triacs drives Circuit has the power limit of three grades so that motor power is restricted to 80%, 75% and 70%.Watt percentage is logical Cross the zero crossing of the setting of triacs firing angle or first half period in supply AC sine waves With triacs is connected in scheduled time delay and completes after point.

If motor rotary speed, under rotating speed of target, 80% can increase motor rotary speed.

85% will be used as rotating speed of target.

If motor rotary speed, on rotating speed of target, 77% can reduce motor rotary speed.

Centrifugal switch can be used in enable touch switch on motor drive shaft, be opened to which triode ac switch be arranged Close the watt limit grade of the triacs of element driving circuit.In the case of no switch contact, Motor by with 85% power with running unit.Contacted by first switch, motor by with 80% power to run list Member.Determination unit is exported rotating speed by the distance between centrifugal switch and first switch contact.It is contacted by second switch, motor By with 75% power with running unit.

It will be appreciated that the simple triacs driving circuit with mechanical separator speed setting With the less electronic building brick controlled for rotating speed, but be to provide limited rotating speed setting grade and the adjustment of limited watt etc. Grade.

Exemplary triacs power (watt) limit with Hall effect speed probe feedback Driving circuit processed is only disclosed by way of example.In this embodiment, output rotating speed is supervised by Hall effect speed probe It surveys.The watt of motor is adjusted being calculated by the comparison from control IC by triacs.Watt is adjusted It is whole can be controlled by triacs firing angle or triacs AC waveforms cut Lai It provides.It will be appreciated that under underload, minimum power will be applied to motor, to generate the torque of requirement, and Under heavy load, whole power will be applied to motor, to generate the torque and rotating speed of requirement.In this embodiment, motor It can be by full power operation, to be tieed up using motor capacity and as long as the enough motor rotary speeds of motor rated power It holds.With enough motor dimensions, the unit output rotating speed of all rotating speeds setting can be maintained.But It is that under the heavy load of slow-speed of revolution setting, total power or motor will be transported to close to total power, and then cause motor temperature fast Speed increases (due to the poor efficiency under the slow-speed of revolution and high torque output).It is right under the high rotating speed setting being arranged with the slow-speed of revolution In the load of such as dough/pasta mixing, the torque and rotating speed that are generated by motor lead to gear failure.

Exemplary motors power control device and method for motor driving triacs include It is arranged and is applied to the different watt limit of motor and each of is arranged for multiple rotating speeds, which is used for Realize the output of high unit rotating speed, overcome the motor fast temperature raising under the heavy load that the slow-speed of revolution be arranged and overcome with The unit gear failure under the high rotating speed setting of load is arranged in the slow-speed of revolution.

By setting/it is pre- it is settled be controlled by processor module when triacs minimum firing angle come The watt limit is established, wherein Hall effect speed probe is as speed feedback.Turned according to the setting target of reference rotation velocity setting The unit of speed exports rotating speed, and triacs firing angle can be adjusted on minimum angles.Alternatively Ground, the watt limit being capable of enabling (for example, across multiple AC periods) by setting/predetermined maximum number (or percentage) Half AC periods and be established.It is referred to according to the unit output rotating speed for the setting rotating speed of target for establishing rotating speed setting, remaining half AC can be activated or disabled.

It will be appreciated that the watt limit can be set to be just above the normal load of unit rotating speed and torque output Lotus watt requires.Under underload and normal load, motor can run to the power of minimum, and then spend longer time Reach temperature extremes.Usually, the time for reaching the motor temperature limit is arranged to the maximum operation of corresponding rotating speed setting Time.Under heavy load, motor can require maximum power to reach the rotating speed of requirement, by the watt limit, the control limit Motor capacity has been made to reach rotating speed of target, while so that motor is operated relatively long before reaching temperature extremes.

It will be appreciated that the unit torque that the watt limit can be set to be just below after being formulated the time is defeated The normal load watt requirement gone out.After being formulated the time, unit no longer needs conveying setting load-torque, but needs to maintain Operation.By the further watt limit, unit can before reaching its motor temperature limit last longer.

Figure 22 shows the flow chart 800 of the method for motor power control.This approach includes the following steps：

Step 810：Data, the data are maintained to indicate each of optional rotating speed setting of multiple users and applied To the respective power limit of motor；

Step 820：Monitoring motor rotating speed, compared with rotating speed setting selected by user；

Step 830：If current rotating speed increases the power for being applied to motor, directly less than rotating speed setting selected by user Reach respective power limit.

Figure 23 shows the flow chart 900 of the method for motor power control.This approach includes the following steps：

Step 902：The equipment is enabled by user.

Step 904：The equipment has launchable power.

Step 906：Identify user setting rotating speed.

Step 908：Once rotating speed setting (for example, from " 1 " i.e. slow-speed of revolution to " 12 " i.e. high rotating speed) selected by user is identified, Then determine respective minimum firing angle or the maximum watt limit；

Step 910：Monitor rotating speed setting, if the equipment operation in the setting rotating speed, back to step 902 with after Rotating speed selected by continuous monitoring user；If the equipment does not operate in the setting rotating speed, step 912 is proceeded to；

Step 912：Identify whether the equipment rotating speed is less than the setting rotating speed, if being less than the setting rotating speed, after Continue step 914；Otherwise step 916 is proceeded to；

Step 914：Firing angle is reduced, but cannot be less than previously determined minimum firing angle and (turn to increase motor Speed), step 902 is returned to, to continue to monitor rotating speed selected by user：

Step 916：Increase firing angle (to reduce motor rotary speed), back to step 902 to continue to monitor user institute Select rotating speed；

It will be appreciated that if user does not change rotating speed setting, identical rotating speed of target will be monitored with tuning Triacs firing angle, to towards object element output rotating speed increase/reduce motor rotary speed.In weight Under load, if rotating speed cannot meet rotating speed of target, firing angle cannot be reduced under least limit, to protect gear And prevent motor from overheating during operation.

Rotating speed setting is turned by being mixed into from the dough/pasta mixing mixed with the heavy load slow-speed of revolution or dessert with underload height The different mixed performances of the albumen mixing of speed mixing determine.With four kinds of rotating speed bands from heavy load to underload：Band 1- Folding is rubbed (rotating speed 1,2,3), and band 2- is gently mixed (rotating speed 4,5,6), and band 3- cream is patted (rotating speed -7,8,9) and beaten with 4- inflations It sends out (rotating speed 10,11,12).

Phase angle can be scheduled to control lower motor temperature rising and make gear assembly in a rotating speed Ability under being arranged is maximum.

For example, in band 1：

Under dough load of most living again, under no watt limit, in the 75% watt limit, the 65% watt limit and Motor temperature is recorded under the 55% watt limit to rise.

According to motor from the duration of 25 DEG C of 120 DEG C of arrival, the watt percentage control of maximum length in time is found.

The 65% watt limit is selected, and the maximum length in time of its temperature extremes is reached because being provided for motor.

The variation of motor locked rotor can be increased more quickly to heat motor by further decreasing watt percentage limits.

After being formulated the time, watt percentage limits can be further reduced to 65% hereinafter, to reduce motor Continue to keep motor operation while heating.

When rotating speed is slack-off, gear assembly can handle maximum load and rotating speed setting.

For example, in band 2：

Under dough load of most living again, under no watt limit, in the 75% watt limit, the 65% watt limit and Under the 55% watt limit, record motor temperature rises.

According to motor from the duration of 25 DEG C of 120 DEG C of arrival, the watt percentage control with maximum length in time is found System.

The 75% watt limit is selected, and the maximum length in time of its temperature extremes is reached because being provided for motor.Ginseng Examining the higher watt limit of band 1 allows preferably to cool down motor.

After being formulated the time, watt percentage limits can be further reduced to 65% hereinafter, to reduce motor Continue to keep motor operation while heating.

When rotating speed is slack-off, gear assembly can handle maximum load and rotating speed setting.

For example, in band 3：

No watt limit and 75% the watt limit under, gear assembly cannot handle most heavy dough formulation.

Under dough load of most living again, under the 65% watt limit and the 55% watt limit, record on motor temperature It rises.

According to motor from the duration of 25 DEG C of 120 DEG C of arrival, the watt percentage control of maximum length in time is found.

The 65% watt limit is selected, and the maximum length in time of its temperature extremes is reached because being provided for motor, and And provide the increased driving torque compared with the 55% watt limit.

After being formulated the time, watt percentage limits can be further reduced to 65% hereinafter, to reduce motor Continue to keep motor operation while heating.

For example, in band 4：

Under dough load of most living again, the 65% watt limit, 55% watt and 45% the watt limit under, note Motor temperature is recorded to rise.

According to motor from the duration of 25 DEG C of 120 DEG C of arrival, the watt percentage control with maximum length in time is found System.

The 45% watt limit is selected, and the maximum length in time of its temperature extremes is reached because being provided for motor, and And it shows the driving torque of the bigger compared with the 55% watt limit.

After being formulated the time, watt percentage limits can be further reduced to 65% or less to reduce motor heating While continue keep motor operation.

With reference to figure 23, only by way of example：

For setting 1, when firing angle is arranged on 49.5 °, motor is only with about 65% whole mean powers, this energy Enough it is sufficiently used for normal operating of the unit to its rotating speed and torque capacity.Under abnormal heavy load, when less power enters horse Up to when, compared with the inactivity limit (e.g., 5 minutes), motor temperature rising is slowed (e.g., 12 minutes).

For setting 2, when firing angle is arranged on 41.4 °, motor is only with about 75% whole mean powers, this energy Enough it is sufficiently used for normal operating of the unit to its rotating speed and torque capacity.Under maximum dough formulation load, when less work( It when rate enters motor, is compared with the inactivity limit (e.g., 10 minutes), motor temperature rising is slowed (e.g., 41 minutes).

For setting 3, when firing angle is arranged on 49.5 °, motor is only with about 65% whole mean powers, this foot It is enough in normal operating of the unit to its rotating speed and torque capacity.

Under abnormal load (e.g., maximum dough formulation load), gear breakage can be reduced, and motor temperature quilt Being continually maintained in its well, respectively the limit assigns the maximum run time of unit.

It will be appreciated that the higher rotating speed from 4 to 12 is arranged, further power (watt) limit can By application to prevent gear failure and motor excess temperature.

It will be further appreciated that the motor dimension (e.g., 550W) of opposite bigger can be selected as desk-top mix Clutch.Advantage can include any one or more of following：

Improve motor on time；

Reduce the risk for damaging gear due to the setting of inappropriate rotating speed under heavy load；

Under normal operating load, desired unit output rotating speed and torque are maintained；

If being used for abnormal heavy load, when limiting torque, the motor using more capacity is enabled, to reduce rotor The risk of locking condition；

When compared with using high torque small-sized motor, cost efficiency is improved.

General motor can be controlled to rise using the motor temperature of improved/reduction as described above, and subtract The risk of few unit gear failure being arranged based on high rotating speed.

As shown in Figure 39 and Figure 40, other than main mixing attachment 1090 (mixing, scraping or stirring attachment etc.), Auxiliary scraping accessory 1091 can be attached to the planetary head 1092 of rotation.In the example of Figure 39 and Figure 40, auxiliary is matched Part 1091 is carried by yoke or collar 1093, and the yoke or collar clamp, is snapped onto on rotatable head 1092 or otherwise It is attached to rotatable head 1092, the action without interfering key fitment 1090.In the example of Figure 39, accessory includes being attached to The undercutter blade 1094 of collar or yoke 1093.Undercutter blade 1094 is configured as and the mixing cup 1095 of cooperation Inner surface carries out linear contact or close contact.The blade section of auxiliary accessories includes the work department of attached doctor blade 1094 Usual vertical and bending the substrate 1096 divided.The substrate 1096 is preferably attached to horizontal arm 1097, the horizontal arm 1097 are attached to clamping collar 1093 or integrally formed with collar 1093 is clamped.In some embodiments, collar 1093 is Separation, and adjacent end part 1098 is attached to each other by fastener 1099, and which can be tightened or twist Pine is to install or remove auxiliary accessories.Therefore, key fitment 10 will comply with the circular rail of the vertical center line around cup 1095 Road, while there is the second rotary motion of longitudinal entrance 1097 around attachment 1090.Such as Figure 40 suggestions, attachment yoke or axis Ring 1091 can have the two or more accessory blades 1100,1101 being attached to thereon, the preferably described blade equidistant Ground is separated.In this example, undercutter or scraper 1100,1101 are carried with one of the output mandrel by mixer Attachment 1102 is stirred to be used in combination.

As shown in Figure 41-43, the mixer of epicyclic type can be provided with two sseparated rotation output mandrels 1110、1112.This provided for mixer and meanwhile rotate two different attachmentes (each with planetary action) ability or The ability of single accessory is rotated in one of two different locations.With reference to the rotation centerline 1113 on planetary head 1114, one Output mandrel 1112 can be seen as being located radially at the outside of another output mandrel 1110.As proposed by Figure 42 and Figure 43, Each output mandrel 1110,1112 is carried by the planetary gear 1113,1114 of their own.Two planetary gears 1113,1114 are mutual It is meshed and is driven jointly by the connection between a planetary gear 1114 and stationary orbit or gear ring 1115.Such as Figure 42 and Shown in Figure 43, main driving axis 1116 terminates in the helical worm 1117 coordinated with gear on worm 1118.Helical worm gear On the vertical axis, the vertical axis also carries reduction gearing 1119 to 1118 carrieds.Reduction gearing 1119 drives by vertical axis The sun gear 1116 of 1121 carryings, the vertical axis 1121 are attached to planet head 1122.Axle journal or 1123, bearing Vertical axis 1121 is supportted consistently to move in planet head 1122 and sun gear 1120.Due to planetary gear 1114 with it is static Track gear ring 1115 intermeshes, therefore the spinning movement on planet head 1122 drives two output mandrels 1110,1112.Often A mandrel 1110,1112 is supported by the axle journal or bearing 1124 being carried in head 1122.

By providing the output mandrel 1110,1112 of two rotations, which provides two for its accessory has difference Planetary orbit, each track have different track maximum effective diameters.Thus, for example, two different cup sizes can Easily accommodated.

Deep narrow diameter cup has been specifically developed to stir albumen, as shown in figure 44.However, mixed for planet For the conventional mixing cup of clutch by the overall maximum caliber with 220mm, the cup of Figure 44 has the maximum caliber 1200 of 171mm.So And the conventional cup that mixes has the overall height (including pedestal) of 178mm, the overall height for the cup described in Figure 44 is 188mm, packet Height containing pedestal 1201.As proposed by Figure 44 and Figure 45, the top of cup profile is similar to vertical.Lower part 1203 is gradually Contracting, near parabolic and incorporates lowest part 1204, and the lowest part 1204 is incorporated with center raised portion 1206A's Narrow annular sink 1205.Lowest part 1204 is supported by pedestal 1201 and is attached to pedestal 1201.It will be further explained It is that pedestal 1201 can have at three in distinguishing orientation to be provided in the pedestal of mixer.Similarly, Figure 44 and Figure 45 Example in cup have incorporate three equidistant recessed 1206A pedestal 1201 and be provided in the pedestal with mixer Spill bayonet lock feature cooperation one or more protrusions 1207.

As shown in figure 46, in order to promote to stir attachment 1210 and can be in the raw-food material (example of the bottom of narrow cup 1211 Such as albumen) between better contact, stir between the routine between 1210 lowest tip and the minimum point 1213 of sink 1205 Gap can be minimized.In this example, once assembled, then gap 1214 is about 4mm.In this example, sink 1205 Minimum point 1213 represented by pitch circle or diameter be about 51.2mm.The swedged cup is about 3-4 quarts.Standard drink About 5-6 quarts.3 quarts of cup is particularly useful for patting egg or mixing the raw material of small size.

As shown in figure 47, it is suitble to the bench mixer 1300 of the planetary-type coordinated from the cup of different sizes 1301,1302 Which can be benefited by sensing accessory 1303,1304 and being attached to output mandrel or mandrel 1305 on planet head.This master If because when by with not desired narrow diameter cup 1302 is used in combination when, attempt to have using major diameter accessory 1303 and do The hidden danger for disturbing or causing other difficult.In this example, bench mixer 1300 is adapted to detect for the type of cup and therefore examines The size of cup is surveyed, and then by the type of the cup detected compared with the type of detected accessory.If cup and accessory are Incompatible, then user will cannot activate the drive motor 1306 of mixer.It is as discussed previously and with reference to figure 44, it is specific Cup (such as narrow diameter cup) have be formed on the recessed 1206A of one or more of pedestal 1201 of cup.Recessed 1206A Presence or shortage can be detected by the mechanical pick-up device 1307 positioned at adjacent openings 1308, the opening 1308 receives cups Pedestal 1201.Preferably, mechanical pick-up device 1307 is by radial oriented and include microswitch, and the microswitch is according to cup Whether pedestal is released or does not discharge comprising recessed 1206A.The sensor 1307 of other forms can be used for detection cup base The distinctive characteristics of seat.Information from sensor 1307 is provided to the microprocessor control unit 1309 of mixer.Therefore, MCU is provided the instruction which cup has been successfully inserted by user.MCU is by the output ratio of the information and accessory sensor 1310 Compared with.Accessory sensor 1310 is located in the pedestal 1311 of mixer, in the boundary of the receiving opening for cup 1308 and excellent Selection of land approaches the First Point of opening 1308.When the vertically or longitudinally entrance of accessory 1303 is directly on sensor 1310, This " beginning " and " completion " for being referred to as accessory 1303 is orientated.In the orientation, accessory 1303 can be introduced in cup 1301 It is interior and when accessory still be attached to output mandrel 1305 when from cup 1301 remove.In this example, doctor blade 1303 has been Through being provided with magnet 1312, the magnet 1312 be located on the longitudinal centre line of attachment 1303 and neighbouring attachment 1313 most Lower part.When magnet 1312 is on sensor 1310 (such as Hall sensor or reed switch), sensor 1310 provides Signal or pulse are to MCU 1309.Therefore, the accessory of signal or pulse instruction with magnet 1312 that sensor 1310 generates 1303 in the orientation on sensor 1310.The shortage of signal indicates that no accessory exists or accessory does not have magnetic to MCU Iron 1312.In this example, sensor is under the lowest part of annular water tank, the annular water tank be inserted into Cup 1301 in receiving opening 1308 is associated.

It brings accessory 1303 into beginning automatically in addition, Figure 47 illustrates that mixer 1300 can be provided with or completes to be orientated In function.In order to accomplish that the function, MCU 1309 allow for being rotationally oriented for detection planet head 1315.In order to accomplish The function, the main body that planet head is provided with magnet 1316 and mixer 1300 are provided with and can detect magnet 1316 Presence or sensor 1317 close to magnet 1316.Further, the main motor 1306 of mixer has output shaft 1318, have mounted thereto magnet ring 1319.Hall effect sensor 1320 coordinates to send signal with magnet ring 1319 To MCU 1309, the signal is interpreted the direct reading of the rotating speed of output shaft 1318.In a preferred embodiment, output shaft 1318 driving reduction gear boxes 1328, the machine driving that reduction gear box 1328 forms connection motor 1306 to main shaft 1329 fill Set 1321 part.
